Hi Toby, yeah i pulled a few fuses to reset the ecu then went on and drove for the adaptation. well, im hoping i did the adaptation right(did it at rush hour and too much traffic)..lol but yeah now the pinging problem..do u think the system will take time to learn? or could this be another problem?my oil level is fine just to eliminate oil pressure from it.

Im pretty sure they are all in correct position. Also i noticed that when i have the AC on the car seems to have lost a lot of power.

That's the way AC works, it runs off power from the engine, so less power output is left going to the tranny.

Why not just put the IPD unit back in if it worked better for your car? Maybe your stock unit has enough miles on it that it is plugged up a little or worn out.

I don't know if this is your problem but you should do a hard reset by actually disconnecting the terminals from the baterry. Then touch the two loose battery terminal ends together for a moment to clear the memory. Reattach the battery terminals and follow the directions for the IPD TCV adaptation. The car will handle it anyways but the adaptation smoothes the learning curve.

You might have a worn out stock TCV or maybe hooked up wrong, left something else unplugged, etc....swap back to IPD and see if it goes away like others have said.

Stock tune? What's the boost gauge doing when this happens?

my concern it that to NJ with stock tune it will be really hard to get some pinging(pre detonation), seems that something is loose there or wrong connected. If the TCV is not working fine it will allow a huge boost peak making a lot of noise.

Yes the car is stock and i dont have a boost gauge. I will try and unplug the battery terminals later but is it possible to just remove the negative terminal and leave it unplugged for a while? Will that do a "hard reset"?

What's keeping you from just removing both and doing it the correct way? The battery is in the trunk if you didn't know.

Alright guys so i did remove the battery terminals and went back to ipd tcv and viola!! Pinging is gone. Well, drove it hard and didnt hear the pinging. Now, im hoping that the ipd tcv will hold up as i bought it used.(and hope it wont do damage to my car). Anyways, does that mean that my stock tcv is toast? See the car was running fine with the stock tcv before i repaced it with the ipd one, and everytime i try the stock one just never felt the same. Anyways, im considering getting the phuzzy tcv cuz i heard people are liking it and its cheaper that the ipd ones. Anyhow i really appreciate all the help u guys have given me.

uuugghhmm.... i know i said the pinging is gone but i may have spoken too soon!lol...could it be something else? would a bad axle cause that noise? i noticed the sound today as i was going uphill and the tranny downshifted from 3rd to 2nd and i have it a bit of gas and it made that noise.

Forgot to mention that my dealer did an "update" for my ecm regarding fuel management or something. I didnt pay for anything so i figured why not. The part number for the software is 30677021. Could this be the culprit?? The thing is i didnt really noticed the ping or detonation right after they did the software. The only time i noticed it was when i was switching tcvs. Is our s60s equipped with knock sensors? Would that trigger the engine light to come on? Im starting to get worried that this could be a big problem.

I am a bit confused as to what exactly your are experiencing...... is this ignition ping(knock, detonation,etc....) or an external sound your hearing?

How do you know it's "pinging"??

Yes two knock sensors, no CEL if minor as the ECU will pull timing, dump fuel, withhold boost, etc....to stop detonation, most of the time you wouldn't even know it was happening. If its bad enough to set a CEL you have something majorly wrong....

I think it might be worthwhile to take it to a dealer or qualified indy if you are this concerned yet not able to pinpoint the source......
